Abolhassan Diba

In 1909, he accompanied his half-brother, Mohammad Mossadegh, to Switzerland and France, where he graduated from the Ecole des Sciences Politiques of the Sorbonne, with a degree in economics and administration.

He married Pouran Vakili and is the father of Farhad and Malektadj Diba who was a relative of the former queen Farah Pahlavi.

In this quest, the following activities are worth mentioning: He was the administrator of a large charity hospital, established by his mother Najmieh.

With all of these endeavours, he never lost sight of the human factor, sending hundreds to be trained abroad in whatever vocation they were employed.

In later life, he was devastated by the Iranian Revolution (1979–1980), which saw the wrecking of all his endeavours and the seizure by the clergy of all his assets, including the Park Hotel (which had grown to a 5-star 500-room complex).
